C9 Generator Set

Design Criteria

The generator set meets transient response and block loading steps as per ISO 8528-5.

Cat Diesel Engines

The four cycle Cat diesel engine combines consistent performance with excellent fuel economy and transient response that meets or exceeds ISO 8528-5. The engines have been designed and built for a wide range of applications and can be optimized for low fuel consumption or low emissions. The engines feature a reliable, rugged, and durable design that has been field proven in thousands of applications worldwide from emergency standby installations to continuously operating power plants.

Cat Diesel Engine Features

  • Reliable, rugged, durable design
  • Field-proven in thousands of applications worldwide
  • Four-stroke-cycle diesel engine combines consistent performance and excellent fuel economy with minimum weight
  • Generators

    The generators used on Cat packages have been designed and tested to work with the Cat engine. The generators are built with robust Class H insulation and provide industry leading motor starting capability. They provide high efficiency in a majority of applications and optional coastal protection for the windings is available for harsh environments.

    Cat Generator Set Packages

    Cat® generator set packages have been fully prototype tested, and certified torsional vibration analysis reports are available. The packages are designed to meet the NFPA 110 requirement for loading, and conform to the ISO 8528-5 steady state and transient response requirements.

    Generator Features

  • Matched to the performance and output characteristics of Cat engines
  • Industry leading mechanical and electrical design
  • Industry leading motor starting capabilities
  • High Efficiency
  • Cat EMCP Control Panel

    The EMCP controller features the reliability and durability you have come to expect from your Cat equipment. EMCP4 is a scalable control platform designed to ensure reliable generator set operation, providing extensive information about power output and engine operation. EMCP4 systems can be further customized to meet your needs through programming and expansion modules.

    Cooling System

    The cooling system has been designed to operate in standard ambient temperatures up to 50°C (122°F) with an air flow restriction of 0.5 in water. The factory installed cooling system has been designed and tested to ensure proper generator set cooling, and includes the radiator, fan, belts, and all guarding installed as standard. Contact your Cat Dealer for specific ambient and altitude capabilities.
